A DESCRIPTION OF THE PROBLEM :
When compiling a class containing the following code:

public <T> void process (Action action, Result<T> results[])
{
    // unrelated problem stuff happens
    Result<T>[] singleResult = results.getClass().cast(Array.newInstance(results.getClass().getComponentType(), 1));
    // more problem-unrelated stuff happens
}

one receives a compiler error similar to:
 [depend] Deleted 38 out of date files in 0 seconds
     [echo] Building...
    [javac] Compiling 142 source files to .../classes
    [javac] .../SomeClass.java:88: incompatible types
    [javac] found : capture#69 of ? extends some.pacakge.Result[]
    [javac] required: some.package.Result<T>[]
    [javac] results.getClass().cast(Array.newInstance(
    [javac] ^
    [javac] Note: Some input files use unchecked or unsafe operations.
    [javac] Note: Recompile with -Xlint:unchecked for details.
    [javac] 1 error

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. create a function that has a generic type passed in.
2. instantiate an array using the component type of a passed-in array argument of the generic type
3. try and cast the newly-instantiated array to the generic type
4. assign the object resulting from step 3 to a reference of the generic type.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
I expected the compiler to successfully compile the code as the JDK 1.5 compiler did.
ACTUAL -
I received a compiler error similar to:
 [depend] Deleted 38 out of date files in 0 seconds

REPRODUCIBILITY :
This bug can be reproduced always.

See description.
---------- END SOURCE ----------

CUSTOMER SUBMITTED WORKAROUND :
For now, I am going to have a 2nd generic type, passed-in as a parameter to the function which can be used as a model of what return type to expect.
